using anonymous functions as callback functions
瞰赽 3. using anonymous functions as callback functions

the callback should return the replacement string.
the behavior of this function is almost identical to preg_replace(), except for the fact that instead of replacement parameter, one should specify a callback that will be called and passed an array of matched elements in the subject string. the callback should return the replacement string.

if you call them from callback function, the behavior is undefined.
ob_end_clean(), ob_end_flush(), ob_clean(), ob_flush() and ob_start() may not be called from a callback function. if you call them from callback function, the behavior is undefined. if you would like to delete the contents of a buffer, return ""(a null string) from callback function.

users may not change the array itself from the callback function. e.g.
odd: array ([a] = 1 [c] = 3 [e] = 5) even: array ([0] = 6 [2] = 8 [4] = 10 [6] = 12)

so only set this entry, if you really want to implement such a callback-function.
see also unserialize().

name of user-defined callback function to be called whenever a stream triggers a notification.

pcntl now uses ticks as the signal handle callback mechanism, which is much faster than the previous mechanism.

if multiple output callback functions are active, output is being filtered sequentially through each of them in nesting order.
output buffers are stackable, that is, you may call ob_start() while another ob_start() is active. just make sure that you call ob_end_flush() the appropriate number of times. if multiple output callback functions are active, output is being filtered sequentially through each of them in nesting order.

an interesting use of this function is to construct an array of arrays, which can be easily performed by using null as the name of the callback function
?php $a = array(1, 2, 3, 4, 5); $b = array("one", "two", "three", "four", "five"); $c = array("uno", "dos", "tres", "cuatro", "cinco"); $d = array_map(null, $a, $b, $c); print_r($d);?

array_map() returns an array containing all the elements of arr1 after applying the callback function to each one.

some functions like call_user_function() or usort() accept user defined callback functions as a parameter.
